Description :


Written for academic chemists working in industrial, government and academic laboratories, this book aims to be the definitive guide to standards, compliance and best practice in absorption spectrometry. Compiled by a distinguished team of authors and co-ordinated by the Ultraviolet Spectrometry Group (UVSG), it is essentially a practising analytical chemists' manual. The underlying theory is covered in outline, with references to more fundamental works. The discussion on standards in the first part represents a consensus of informed user opinion and is independent of any commercial bias. The second part contains a guide to the practical application of UV spectrometry written by recognised experts in the field. Part 1 Standards: Overview of UV spectrometry, cell design and construction, instrument design, liquid absorbance standards, solid absorbance standards, stray light, wavelength standards, regulatory overview, recommended procedures for standardisation. Part 2 Practical Absorption Spectrometry: Absorption spectrometry in practice, measuring the spectrum, chemometric techniques and numerical methods, derivative techniques, and automated sampling.

Description :


The determination of the concentrations of molecules in samples has long been an important application of spectroscopy. In the last 20 years advances in algorithms, computers, instruments, and software have led to a growing interest in this field. These developments mean samples and analytes that were once considered intractable are increasingly yielding usable calibrations. The purpose of this book is to give readers, without an advanced math background, a thorough grounding in the theory and practice of modern quantitative spectroscopic analysis. The author has placed great emphasis on providing the reader with everything they need to know to obtain a fundamental understanding of quantitative spectroscopy. · Relevant theory is explained in an easy to understand, conversational style. · Actual spectroscopic data and calibrations are used throughout the book to show how real world calibrations are achieved. · The complexities of Factor Analysis (PCR/PLS) algorithms are explained in pictures and words, making them understandable for all. · Written from a spectroscopic rather than a mathematical point of view. · Relevant theory is interspersed with practical discussions in order to make difficult concepts easier to comprehend · It is a comprehensive introduction for novices, and an excellent reference for experts. · Topics on spectroscopy are included to emphasize its importance in quantitative spectroscopy

Despite the existence of many competitive analytical techniques, molecular absorption spectrophotometry still remains very popular in practice, particularly in biochemical, clinical, organic, agricultural, food and environmental analyses. This is due mainly to the inherent ease and relative simplicity of spectrophotometric procedures and the availability of reliable and highly-automated instruments. Moreover, the method and its instrumentation has recently undergone considerable development resulting in some new special approaches of spectrophotometry in the ultraviolet (UV) and visible (VIS) regions. Although there are a number of comprehensive textbooks dealing with UV/VIS spectrophotometry, they tend to describe historical aspects or contain collections of detailed procedures for the determination of analytes and do not reflect sufficiently the present state of the method and stage of development reached. This book provides a concise survey of the actual state-of-the-art of UV/VIS spectrophotometry. Special attention has been paid to problems with the Bouguer-Lambert-Beer law, absorption spectra, present trends in instrumentation, errors in spectrophotometry, evaluation of analyte concentration and calibration, optimization procedures, multicomponent analysis, differential spectrophotometries, problem of blanks, derivative and dual-wavelength spectrophotometry, spectrophotometric titration, the strong relations between complex formation and spectrophotometry, spectrophotometric investigation of complex equilibria and stoichiometry or automation in spectrophotometry. The significance of spectrophotometry in connection with liquid-liquid extraction, reaction kinetics, trace analysis, environmental and clinical analysis is also covered. The text is supported by tables and figures, and numerous references are provided for each topic treated. The book is written for all those who use UV/VIS spectrophotometry in the laboratory and will also be useful to students as supplementary reading.

Description :


The inspiration for this volume lies in Edisbury's Practical Hints for Absorption Spectrometry which was published 17 years ago. Dr Edisbury was a founding member of the Photoelectric Spectrometry Group, served as its first Secretary and edited the Bulletin for many years. His wisdom, humour and pragmatism was evident in early meetings of the Group and in the first issues of the Bulletin, and these qualities were distilled in the writing of Practical Hints. In 1977, the Committee of the Group, which by then had been re-named The UV Spectrometry Group, decided to make use of the expertise available amongst the members of the Group in writing some monographs on the practice of UV and visible spectrometry. Working parties were set up which formulated and produced the first two volumes of the series on Standards in Absorption Spectrometry and Standards in Fluorescence Spectrometry. The success of these volumes lead the present Committee of the Group to set up a new Working Party in 1981 to plan a modern version of Edisbury's book. The idea really caught fire' at the first meeting of the Working Party, when ideas sufficient to fill ten vol umes were put forward. We would not pretend to emulate Edisbury's unique style, but hoped to produce a readable book for the newcomer to UV -visible absorption spectrometry, and perhaps to improve the technique of more experienced users.

Description :


Since the first edition of this book was published early in 1970, three major developments have occurred in the field of x-ray spectrochemical analysis. First, wavelength-dispersive spectrometry, in 1970 already securely established among instrumental analytical methods, has matured. Highly sophisticated, miniaturized, modular, solid-state circuitry has replaced elec tron-tube circuitry in the readout system. Computers are now widely used to program and control fully automated spectrometers and to store, process, and compute analytical concentrations directly and immediately from ac cumulated count data. Matrix effects have largely yielded to mathematical treatment. The problems associated with the ultralong-wavelength region have been largely surmounted. Indirect (association) methods have extended the applicability of x-ray spectrometry to the entire periodic table and even to certain classes of compounds. Modern commercial, computerized, auto matic, simultaneous x-ray spectrometers can index up to 60 specimens in turn into the measurement position and for each collect count data for up to 30 elements and read out the analytical results in 1--4 min-all corrected for absorption-enhancement and particle-size or surface-texture effects and wholly unattended. Sample preparation has long been the time-limiting step in x-ray spectrochemical analysis. Second, energy-dispersive spectrometry, in 1970 only beginning to assume its place among instrumental analytical methods, has undergone phenomenal development and application and, some believe, may supplant wavelength spectrometry for most applications in the foreseeable future.
